This thesis will try to describe all the stages and activities that occur during the production of a computer game. The production plan used here will cover all the important areas that affect the success of the project and can be used with both small and large teams. The first chapter presents a brief introduction, the state of the industry, and the issues of the given topic. The problems mentioned above apply especially to inexperienced teams just entering the industry. The second chapter lists and describes all the methodologies used in the industry today. Through these descriptions (advantages and disadvantages) we can clearly conclude why agile methodologies have changed from standard methodologies and how they improve project operation and management. In chapter three we go through all the phases of the project. We will notice that the pre-production phase serves as the basis of the project and, if successfully completed, facilitates the rest of the project and reduces the risks during production. This is mainly because at the end of the pre-production we have to have a game design document (GDD or Game design document) and a technical specification document that are a fundamental part of the production phase. In the production phase, we see that the work takes place in iterations that last for several months and at the end of each iteration we have a new version of the game. Aside from the technical work, here goes the marketing of the game. The post-production phase and the quality assurance phase (QA) serve to polish the product, promote it, and resolve any legal issues. At the end of these stages, you should have a game ready for release. In conclusion, I give my opinions and observations on the topic. Current situation and assumed direction of movement of the industry. A special part of this paper is the description of the producer's role and the analysis of the game market and the trends that dictate production. The producer is the most important person for managing and succeeding in the project. He must be the one to encourage and motivate the team when things get tough. In analyzing the market, an important role is played by the publisher, who takes care of the sale and distribution of games.
